A recent discovery of spotted lanternflies in St. Catharines, Ontario, has reignited concerns about this destructive insect potentially infiltrating Canada from the United States. While Canada does not currently have established spotted lanternfly populations, experts warn that the invasive insect could severely impact vineyards, fruit trees, and hardwoods due to its feeding habits and ability to harm grapevines.
Aidan Dagg, a resident of Ontario and a nursery inspector in St. Catharines, recently found a deceased spotted lanternfly and promptly reported it on iNaturalist, a platform for identifying plants and animals. This marked Dagg’s first encounter with the insect after keeping an eye out for it over the past few years.
According to Diana Mooij from the Canadian Food Inspection Agency (CFIA), spotted lanternflies can feed on over 100 tree and plant species, posing a significant threat to the grape and wine industries. Upon Dagg’s report to the CFIA, inspectors swiftly responded by collecting 12 dead adult lanternflies from an imported shipment of planting pots originating from Pennsylvania.
Research scientist Amanda Roe explained that spotted lanternflies often travel in shipments and can easily hitchhike on vehicles, particularly those returning from the U.S. Roe emphasized the insect’s ability to latch onto flat surfaces and move across long distances. The spotted lanternfly, initially detected in the U.S. in 2014, has since spread to 19 states, causing substantial economic losses if left unchecked.
Notably, the insect’s resilience to various climates poses a challenge for containment efforts. Melody Keena, a retired research entomologist, highlighted the spotted lanternfly’s adaptability to warmer temperatures, facilitating their population growth. Despite the harsh winter conditions in some regions, the insect has shown remarkable survival capabilities, raising concerns about its potential spread into Canada.
As authorities advise vigilance in spotting and reporting spotted lanternflies, it is evident that proactive measures are crucial to prevent the further proliferation of this invasive species.
